2. Ceramic heater - Wikipedia

   en.wikipedia.org/wiki/Ceramic_heater

   A ceramic heater as a consumer product is a space heater that generates heat using a heating element of ceramic with a positive temperature coefficient (PTC). [1] [2] [failed verification] Ceramic heaters are usually portable and typically used for heating a room or small office, and are of similar utility to metal-element fan heaters.

3. Thermal management of high-power LEDs - Wikipedia

   en.wikipedia.org/wiki/Thermal_management_of_high...

   A TE device made by two ceramic plates can be integrated into a high power LED and adjust the temperature of LED by heat-conducting and electrical current insulation. [10] Since ceramic TE devices tend to have a coefficient of thermal expansion mismatch with the silicon substrate of LED, silicon-based TE devices have been invented to substitute ...

4. Resistance thermometer - Wikipedia

   en.wikipedia.org/wiki/Resistance_thermometer

   Resistance thermometers, also called resistance temperature detectors (RTDs), are sensors used to measure temperature. Many RTD elements consist of a length of fine wire wrapped around a heat-resistant ceramic or glass core but other constructions are also used. The RTD wire is a pure material, typically platinum (Pt), nickel (Ni), or copper ...

5. Heat flux sensor - Wikipedia

   en.wikipedia.org/wiki/Heat_flux_sensor

   Another possibility to minimize the temperature dependence of a heat flux sensor, is to use a resistance network with an incorporated thermistor. The temperature dependence of the thermistor will balance the temperature dependence of the thermopile. Another factor that determines heat flux sensor behavior, is the construction of the sensor.

6. Silicon bandgap temperature sensor - Wikipedia

   en.wikipedia.org/wiki/Silicon_bandgap...

   The silicon bandgap temperature sensor is an extremely common form of temperature sensor (thermometer) used in electronic equipment. Its main advantage is that it can be included in a silicon integrated circuit at very low cost.

7. Thermistor - Wikipedia

   en.wikipedia.org/wiki/Thermistor

   A thermistor is a semiconductor type of resistor in which the resistance is strongly dependent on temperature. The word thermistor is a portmanteau of thermal and resistor.The varying resistance with temperature allows these devices to be used as temperature sensors, or to control current as a function of temperature.

8. Thermopile laser sensor - Wikipedia

   en.wikipedia.org/wiki/Thermopile_laser_sensor

   Figure 2: [8] Working principle of a thermal laser sensor (Adapted from figure 3 with permission) As shown in Fig 2, a thermopile laser sensor consists of several thermocouples connected in series with one junction type (hot junction at temperature T 1) being exposed to an absorption area and the other junction type (cold junction at temperature T 2) being exposed to a heat sink.

9. Self-regulating heater - Wikipedia

   en.wikipedia.org/wiki/Self-regulating_heater

   If the heat required to hold the desired temperature is known, a PTC heating element can be selected to provide the correct amount of heat at the desired temperature. Such a heating element will warm up quickly because it produces more heat at low temperatures.
